Hi there,

I used to use a Boots facial wash and Nivea Creme. I liked them both but my skin is often dry and blemished and uncomfortable. I do have mild rosacea caused by excessive blushing.

I moved over to La Roche Posay - Toleriane Dermo Cleanser and Physiological Gel followed by Hydreane Riche. My skin has never been more blemished and uncomfortable.

My question is, How long should I persevere with a new product range before stopping??
